摘　　要：本文从计算矿石损失贫化值改变引起采出矿石中矿岩量的变化入手,计算矿石损失贫化变化前后经济效果的差异,对有不同损失贫化值的方案进行了经济评价与分析,并通过计算实例说明了各主要因素对方案损失贫化综合经济效果的影响。本文所推荐的方法为矿石损失贫化的经济评价与分析以及矿山企业现行矿石损失贫化指标合理性的探讨提供了一种较为简便的方法。Starting with calculation of the change of ore and rock tonnages in mined ore, the author calculates the differences of economic results before/after the change of ore loss and dilution, economically analyses and evaluates different schemes for ore loss and dilution. This paper demonstrates the major factors which influence the comprehensive economic results of schemes for ore loss and dilution with actually calculated cases. The method recommended in this paper is a simple one to economically evaluate and analyse the ore loss and dilution and discuss the reasonableness of current ore loss and dilution indicators for mine enterprises.
